EJ ECTO R.

SPECIFICATION forming part of Letters Patent No. 297,615, dated April 29, 1884. Application filed June 25,1883. (ModeL) To all whom it may concern:

Be it known that I, JOHN M. MARTY, a citizen of the United States, residing at Glarksville,- in the county of Johnson and State of Arkansas, haveinvented certain new and use: ful Improvements in Ejectors; and I do here-- by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in steam-jet ejectors; and it consists in making the body or bodies in halves, suitably jointed and held together'partly by bolts and nuts or screws, and partly by the pipe-connections, which screw over the ends of the bodies of the same, thus being additional help to the screws or bolts and nuts. r

In the accompanying drawings,Figure1 represents the ejector with one-half of the casing removed. Fig. 2 represents cross-section of ejector cut through the center of the suction-pipe. Fig. 3 is an edge view of ejector, looking at the end of the suction-pipe, showing the two halves A and Br. and the nuts and bolts, and the upper and lower ends of .cylinders a andy.

' In Fig. 1, A is one half of the casing. The other half (shown in Fig. 3 by letter B) coincides with half A in every particular. or is the suction-hole. n is. the steam-inlet, and 0 the discharge. at is the steam-cylinder, and 3/ the discharge-cylinder. These two cylinders :10 and y are ground to ,fit in their respective. beds quite loosely, so that they will drop down of their own weight. When so dropped, the water in the ejector will drain out, passing at the, opening 0. These cylinders y and a: each have two shoulders, y g andx m The shoulder a is ground exactly to fit against the lower shoulder of its cylinder-bed n, and the shoulder is ground exactly to fit against the lower steam is put on, cylinders y and 00 have their shoulders y" and 00* thrown against the shoulders of their respective beds, and are perfectly tight, so that no steam can pass except through the openings of these cylinders. steam is cutoff, they drop down again, as seen in Figs. 2 and 3, and allow the water to drain out of the ejector.

The two halves A and B of the casing are joined together by bolts and nuts-a, passing through holes b and the piping, which is screwed on the threaded ends of the ejector.

Having thus described my invention, what I shoulder of its cylinder-bed 0'. When the When the claim as novel, and desire to secure by Letters Patent, is

1. In a steam jet or ejector, the casing made in two parts, A and B, exactly coinciding with each other, and held together by bolts and nuts on or screwspassing through the holes I), each half having grooves so cut on its'inner face that when joined together, as described, they will form suctionhole m, and cylinder-beds n 0,

having shoulders, substantially as shown and described, and for the purposes set forth.

2. .In a steam jet or ejector, .cylindersacand 3 ground to fit'loosely in their respective beds n and o, and having shoulders x m M, substantially as shown and described, and for the purposes set forth.

3. In a steam jet or ejector,the combination of half-casing A with tubes 00 and 3 ground loosely in their respective beds 12 0, and having shoulders x m y y", with half-casingB exactly coinciding with half-casing A, and all secured together by bolts and nuts a, substantially as shown and described, and for the purposes set forth.

JOHN M. MARTY.
